我正在try 循环并获取目录中的文件，但在实现它时遇到了一些困难.如何拉入多个文件，然后将它们移动到另一个文件夹？
var dirname = 'C:/FolderwithFiles';
console.log("Going to get file info!");
fs.stat(dirname, function (err, stats) {
if (err) {
return console.error(err);
}
console.log(stats);
console.log("Got file info successfully!");
// Check file type
console.log("isFile ? " + stats.isFile());
console.log("isDirectory ? " + stats.isDirectory());
});
您希望使用fs.readdir函数获取目录内容，使用fs.rename函数实际进行重命名.如果您需要等待这两个函数完成后再运行代码，那么这两个函数都有同步版本.
我写了一个很快的脚本，按照你的描述.
var fs = require('fs');
var path = require('path');
// In newer Node.js versions where process is already global this isn't necessary.
var process = require("process");
var moveFrom = "/home/mike/dev/node/sonar/moveme";
var moveTo = "/home/mike/dev/node/sonar/tome"
// Loop through all the files in the temp directory
fs.readdir(moveFrom, function (err, files) {
if (err) {
console.error("Could not list the directory.", err);
process.exit(1);
}
files.forEach(function (file, index) {
// Make one pass and make the file complete
var fromPath = path.join(moveFrom, file);
var toPath = path.join(moveTo, file);
fs.stat(fromPath, function (error, stat) {
if (error) {
console.error("Error stating file.", error);
return;
}
if (stat.isFile())
console.log("'%s' is a file.", fromPath);
else if (stat.isDirectory())
console.log("'%s' is a directory.", fromPath);
fs.rename(fromPath, toPath, function (error) {
if (error) {
console.error("File moving error.", error);
} else {
console.log("Moved file '%s' to '%s'.", fromPath, toPath);
}
});
});
});
});
在我的本地机器上测试.
node testme.js
'/home/mike/dev/node/sonar/moveme/hello' is a file.
'/home/mike/dev/node/sonar/moveme/test' is a directory.
'/home/mike/dev/node/sonar/moveme/test2' is a directory.
'/home/mike/dev/node/sonar/moveme/test23' is a directory.
'/home/mike/dev/node/sonar/moveme/test234' is a directory.
Moved file '/home/mike/dev/node/sonar/moveme/hello' to '/home/mike/dev/node/sonar/tome/hello'.
Moved file '/home/mike/dev/node/sonar/moveme/test' to '/home/mike/dev/node/sonar/tome/test'.
Moved file '/home/mike/dev/node/sonar/moveme/test2' to '/home/mike/dev/node/sonar/tome/test2'.
Moved file '/home/mike/dev/node/sonar/moveme/test23' to '/home/mike/dev/node/sonar/tome/test23'.
Moved file '/home/mike/dev/node/sonar/moveme/test234' to '/home/mike/dev/node/sonar/tome/test234'.
受ma11hew28答案(shown here)的启发，这里的内容与上面相同，但fs.promises中的异步函数.正如ma11hew28所指出的，与v12中添加的fs.promises.opendir相比，这可能有内存限制.12.0.
下面是快速代码.
//jshint esversion:8
//jshint node:true
const fs = require( 'fs' );
const path = require( 'path' );
const moveFrom = "/tmp/movefrom";
const moveTo = "/tmp/moveto";
// Make an async function that gets executed immediately
(async ()=>{
// Our starting point
try {
// Get the files as an array
const files = await fs.promises.readdir( moveFrom );
// Loop them all with the new for...of
for( const file of files ) {
// Get the full paths
const fromPath = path.join( moveFrom, file );
const toPath = path.join( moveTo, file );
// Stat the file to see if we have a file or dir
const stat = await fs.promises.stat( fromPath );
if( stat.isFile() )
console.log( "'%s' is a file.", fromPath );
else if( stat.isDirectory() )
console.log( "'%s' is a directory.", fromPath );
// Now move async
await fs.promises.rename( fromPath, toPath );
// Log because we're crazy
console.log( "Moved '%s'->'%s'", fromPath, toPath );
} // End for...of
}
catch( e ) {
// Catch anything bad that happens
console.error( "We've thrown! Whoops!", e );
}
})(); // Wrap in parenthesis and call now
